Distributor Assembly Replacement

Description:

Removal Procedure

Notice: If the distributor is removed from the engine, it can be re-installed using Procedure A as long as the crankshaft has not rotated from the original position. If the intake manifold, the cylinder head the crankshaft, the camshaft, the timing gear, or the complete engine was removed or replaced, Procedure B must be followed in order to correctly install the distributor. A DTC code may also indicate an incorrectly installed distributor and engine or distributor damage may occur. Procedure B must then be used.

1. Turn OFF the ignition switch.
2. Remove the spark plug and the coil leads from the distributor cap.
3. Remove the three-wire hall effect switch connector from the base of the distributor.
4. Remove the two screws holding he cap to the housing.

Important: Use a grease pencil in order to not the position of the rotor segment in relation to the distributor housing. Identify the mark with the number 1.

5. Remove the distributor cap.
6. Remove the mounting clamp hold down bolt.
7. Remove the distributor.
8. As the distributor is being removed from the engine, you will notice the rotor move in a counter-clockwise direction, 42 degrees. This will appear as slightly more than one clock position. Noting the position of the rotor segment, by placing a second mark on the base of the distributor, will aid in achieving proper rotor alignment during the distributor installation. Identify the second mark on the base with the number 2.

Installation Procedure A

1. Remove the new distributor cap.
2. Using a grease pencil, place two marks on the new distributor housing in the same location as the two marks on the original housing.
3. When installing the distributor, align the rotor segment with the number 2 mark on the base of the distributor.
4. Guide the distributor into place, making sure the mounting hole in the distributor hold down base is aligned over the mounting hole in the intake manifold.
5. As the distributor is being installed, you will notice the rotor will move in a clockwise direction, 42 degrees.
6. Once the distributor is completely seated, the rotor segment should be aligned with the number 1 mark on the base. If the rotor segment is not aligned with the number 1 mark, the gear teeth of the distributor and the camshaft have meshed one or more teeth out of time. In order to correct this condition, remove the distributor and reinstall it following

Installation Procedure B

7. Install the cap and the mounting screws. Do not overtighten as the boss may strip.
8. Install the distributor mounting clamp and tighten to the proper torque.

Tighten

^ Tighten the distributor clamp and the bolt to 27 Nm (20 lb. ft).

^ Tighten the distributor cap screws to 4.8 Nm (43 lb. in).

9. Install the three wire hall effect switch connector to the base of the distributor.
10. Install the spark plug and the coil leads to the distributor cap.

If a check engine light is illuminated after installing the distributor and a DTC P1345 is found, the distributor has been installed incorrectly. Refer to Procedure B for proper distributor installation.

Installation Procedure B

1. Bring the engine up to Top Dead Center (TDC) of the cylinder number 1. Ensure it is on the compression stroke.
2. Remove the distributor cap screws and the cap to expose the rotor.
3. Align the pre-drilled indent hole in the distributor driven gear with the white alignment line on the lower portion of the shaft housing.
4. The rotor segment should point to the cap hold down mount nearest the flat side of the housing.
5. Using a long screw driver, align the oil pump drive shaft to the drive tab of the distributor.
6. Guide the distributor into place, ensuring that the spark plug towers are perpendicular to the centerline of the engine.
7. Once the distributor is fully seated, the rotor segment should be aligned with the pointer cast into the distributor base. This pointer will have 6 cast into it, indicating that the distributor is to be used on a 6 cylinder engine. If the rotor segment does not come within a few degrees of the pointer, the gear mesh between the distributor and the camshaft may be off a tooth or more. If this is the case, repeat the procedure again in order to achieve proper alignment.

8. Install the cap and the mounting screws. Do not overtighten as the boss may Strip.
9. Install the distributor mounting clamp and tighten to the proper torque.

Tighten

^ Tighten the distributor clamp and the bolt to 27 Nm (20 lb. ft).
^ Tighten the distributor cap screws to 4.8 Nm (43 lb. in).

10. Install the three wire hall effect switch connectors to the base of the distributor.
11. Install the spark plug and the coil leads to the distributor cap.

If a check engine light is illuminated after installing the distributor and a DTC P1345 is found, the distributor has been installed incorrectly.
